Abstract

The invention belongs to the field of cosmetics, and particularly relates to sun cream for sensitive skin. The sun cream for the sensitive skin is characterized by comprising the following raw materials in parts by weight: 30-45 parts of Bama mineral water, 5-8 parts of Caulis Echinopsis Multiplicis extract, 10-15 parts of Folium Pini extract, 1-2 parts of vitamin C, 2-5 parts of vitamin E, 1-3 parts of apigenin, 1-4 parts of acacetin, 2-4 parts of glutathione, 3-5 parts of lycopene, 2-6 parts of glycerol, 2-4 parts of olive oil and 2-5 parts of phenyl phenol. The sun cream for the sensitive skin has the advantages that the natural and non-irritant raw materials without a preservative or sensitization ingredients are selected, UVB and UVA are obstructed effectively, the skin can further be protected against being attacked by free radical, and the sun cream is smooth and anti-irritation, and is particularly suitable for being used as a sunscreen product for highly sensitive skin with poor tolerance.
